Highly effective way in five-axis sculptured surfaces machining using flat-end cutter [PDF]

open access: yes, 2007
This paper applied the concept of “contact” in Differential Geometry into the machining of the sculptured surface. I presented the contact principle of the machining of complicated surfaces, using the circumference circle of the cylindrical cutter to ...

Understanding and Optimizing Li Substitution in P2‐Type Sodium Layered Oxides for Sodium‐Ion Batteries

open access: yesAdvanced Functional Materials, EarlyView.
This work explores Li‐substituted P2 layered oxides for Na‐ion batteries by crystallographic and electrochemical studies. The effect of lithium on superstructure orderings, on phase transitions during synthesis and electrochemical cycling and on the interplay of O‐ versus TM‐redox is revealed via various advanced techniques, including semi‐simultaneous

Enhancing Low‐Temperature Performance of Sodium‐Ion Batteries via Anion‐Solvent Interactions

open access: yesAdvanced Functional Materials, EarlyView.
DOL is introduced into electrolytes as a co‐solvent, increasing slat solubility, ion conductivity, and the de‐solvent process, and forming an anion‐rich solvent shell due to its high interaction with anion. With the above virtues, the batteries using this electrolyte exhibit excellent cycling stability at low temperatures. Abstract Sodium‐ion batteries

Comparative analysis of milling results on the tail-end reduction passages of the wheat flour milling process: Conventional vs. eight-roller milling system [PDF]

open access: yesHemijska Industrija, 2015
Introduction of the eight-roller mill into the wheat flour milling process significantly reduces the investment costs and overall energy requirements compared to the conventional milling system. However, the conditions for controlled milling are

The Rainbow Site, An Unusual Syrup Mill in Gregg County, Texas [PDF]

open access: yes, 2005
The Rainbow site is a historic archaeological site that was recorded during a cultural resources survey of a proposed Wal-Mart SuperCenter site in Longview, Texas. It was first interpreted as the location of an illegal whiskey still, but testing revealed

Unlocking Ultra‐Long Cycle Stability of Li Metal Electrode by Separators Modified by Porous Red Phosphorus Nanosheets

open access: yesAdvanced Functional Materials, EarlyView.
Coating the standard polypropylene separator with a porous red phosphorous nanosheet greatly improves cycling performance in Li electrode cells. The phosphorus‐based surface chemistry deactivates electrolyte solvent decomposition and enhances the cleavage of F‐containing salt, resulting in an inorganic‐dominated electrolyte interphase (SEI) composition

Performance of laser assisted micro-milling (laμmill) of titanium alloy using micro ball end mill [PDF]

open access: yes, 2018
Laser assisted milling technique turns to be complicated and unpredictable when the machining size is scaled to micro level. Furthermore, less has been reported on the application of ball end mill in laser assisted micro milling.
